  the power device, main parts of Transmission System, rotary mechanism, auxiliary equipment and cab of the commonly used full rotary hydraulic excavator are installed on a rotatable platform, which is usually called the upper turntable. Therefore, the single bucket hydraulic excavator can be summarized into three parts: working device, upper turntable and walking mechanism. The transmission system of single bucket hydraulic excavator transmits the output power of diesel engine to working device, rotary device, walking mechanism, etc. There are many types of hydraulic transmission systems for single bucket hydraulic excavators, which are usually classified according to the number of main pumps, the adjustment mode of power and the number of circuits. There are single pump or double pump single loop quantitative system, double pump double loop quantitative system, multi-pump multi-loop quantitative system, double pump double loop power adjustment variable system, double pump double loop full power adjustment variable system, six types of multi-pump multi-loop quantitative or variable mixing systems. According to the oil circulation mode, it is divided into open system and closed system. It is divided into series system and parallel system according to oil supply mode.

Experimental purpose: 1. Combined Boom 2. Change of air transmission pressure
experimental cognition:
     wooden frame: rolling pendulum integral support structure
     suction tube: fixed rope
experimental steps:
           1. Experiment preparation know experimental apparatus: wooden frame, straw.

Experiment report:
            the advantages of integral boom are simple structure, light weight and large rigidity. Its disadvantage is that there are few working devices to be replaced and its versatility is poor. It is mostly used on excavators with similar long-term working conditions. The integral moving arm can be divided into two types: straight moving arm and curved moving arm. The direct moving arm is simple in structure, light in weight and convenient to manufacture. It is mainly used for hanging excavators, but it cannot be used for general excavators to obtain larger excavation depth; bending arm is currently a widely used structural form at present. Compared with the direct moving arm in the same factory, it can make the excavator have a larger excavation depth, but reduce the unloading height, this is in line with the requirements of excavator backhoe operation.
